What they discovered: Their findings, published in the Journal of Archaeological Science, show that wasabi vapors can eradicate microbial growth, particularly of fungi, in both painted and non-painted papyrus samples with an “inhibition efficiency of 100%.” 一個國際科學家團隊發現芥末或日本辣根是壽司的著名佐料，可以處理和保存古埃及紙莎草。他們的發現：他們的研究結果發表在《考古科學雜誌》上，表明芥末蒸氣可以消除塗漆和未塗漆紙莎草樣品中的微生物生長，特別是真菌，“抑制效率為 100%”。 Microbes are known to damage papyrus, a material used in ancient Egypt, as well as ancient Greece and the Roman Empire, for documentation. The scientists also found that wasabi increased the tensile strength of the samples by 26% without changing their painted color or damaging them. How the study was conducted: For the experiment, the scientists used a mixture of wasabi powder and distilled water, which they turned into a “ dumpling-like state.” For the test subjects, they used papyrus replicas painted red, yellow and blue. They then put the replicas into an oven for 120 days to mimic the aging process before exposing them to various fungal specimens commonly found on archeological papyri. 眾所周知，微生物會損壞紙莎草，紙莎草是古埃及、古希臘和羅馬帝國用於記錄的材料。科學家還發現，芥末使樣本的拉伸強度提高了26%，而不會改變其塗漆顏色或損壞它們。研究如何進行：在實驗中，科學家使用了芥末粉和蒸餾水的混合物，將其製成「餃子狀」。對於測試對象，他們使用了塗成紅色、黃色和藍色的紙莎草複製品。然後，他們將複製品放入烤箱中120 天，以模擬老化過程，然後將它們暴露在考古紙莎草紙上常見的各種真菌標本中。 The replicas were then exposed to wasabi vapor for three days, which yielded positive results. The scientists conducted a follow-up a month later and saw similar results. How it’s possible: The scientists attributed wasabi’s anti-fungal effects to allyl isothiocyanate (AITC), a chemical compound and colorless oil that gives wasabi its pungent taste. AITC is known for having antimicrobial properties against various microorganisms. What’s next: The discovery promises a cost-effective and more sustainable alternative for preserving papyri. In the future, the method may also be used to test on other materials such as wood and paper. 然後將複製品暴露在芥末蒸氣中三天，產生了積極的結果。一個月後，科學家們進行了一項追蹤調查，並看到了類似的結果。怎麼可能：科學家將芥末的抗真菌作用歸因於異硫氰酸烯丙酯（AITC），這是一種化合物和無色油，賦予芥末辛辣的味道。AITC 因具有針對多種微生物的抗菌特性而聞名。接下來：這項發現有望為保存紙莎草提供一種經濟有效、更永續的替代方案。將來，該方法還可以用於測試木材和紙張等其他材料。 5.完整新聞連結 (或短網址)不可用YAHOO、LINE、MSN等轉載媒體: https://nextshark.com/wasabi-treat-preserve-ancient-egyptian-papyrus 6.備註: [是骨董，但是會辣。] 舒巴大叔沒這麼說過 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 220.135.156.198 (臺灣) ※ 文章網址: https://www.ptt.cc/bbs/Gossiping/M.1709204456.A.AD2.html
